Colombia (IPA: /kəˈlʌmbɪə/) officially the Republic of Colombia (Spanish: República de Colombia?·i, Spanish pronunciation: [re̞ˈpuβ̞lika ð̞e̞ ko̞ˈlõ̞mbja]), is a country located in northwestern South America. Colombia is bordered to the east by Venezuela and Brazil; to the south by Ecuador and Peru; to the north by the Atlantic Ocean, through the Caribbean Sea; to the north-west by Panama; and to the west by the Pacific Ocean. Colombia also shares maritime borders with Jamaica, Haiti, the Dominican Republic, Honduras, Nicaragua and Costa Rica. Colombia is the 26th largest nation in the world and the fourth largest in South America (after Brazil, Argentina, and Peru), with an area more than twice that of France. It also has the 29th largest population in the world and the second largest in South America, after Brazil. Colombia has the third largest Spanish-speaking population in the world after Mexico and Spain. The territory of what is now Colombia was originally inhabited by indigenous tribes which had migrated from North and Central America, including the Muisca, Quimbaya, and Tairona. The Spanish arrived in 1499, and initiated a period of conquest and colonisation which ultimately led to the creation of the Viceroyalty of New Granada (comprising what is now Colombia, Venezuela, Ecuador and Panama) with its capital at Bogotá. Independence from Spain was won in 1819, but by 1830 "Gran Colombia" had collapsed with the secession of Venezuela and Ecuador. Modern day Colombia, with Panama, emerged as the Republic of New Granada. The new nation experimented with federalism as the Granadine Confederation (1858), and then the United States of Colombia (1863), before the Republic of Colombia was finally declared in 1886. Panama seceded in 1903. Colombia is a standing middle power with the fourth largest economy in South America. It is very ethnically diverse, and the interaction between descendants of the original native inhabitants, Spanish colonists, African slaves and twentieth-century immigrants from Europe and the Middle East has produced a rich cultural heritage. Colombia is the 26th largest nation in the world and the fourth largest country in South America. Located in the northwestern region of South America, it is bordered to the east by Venezuela and Brazil; to the south by Ecuador and Peru; to the north by the [[ Colombia is part of the Pacific Ring of Fire, a region of the world subject to earthquakes and volcanic eruptions. Colombian surface features are varied; in the extreme west are the narrow and discontinuous Pacific coastal lowlands, which are backed by the Serranía de Baudó, one of the lowest and narrowest of Colombia's mountain ranges. The broad region of the Río Atrato/Río San Juan Lowland is another major land region.
